chorioptic mange - treatment

[Scottish_Miss]

Hi

I have spoken to my vet and described what Moo has which is scabbing behind the knees - worse on one leg, softening them helps but not clearing them, someone on here said it was mallanders but my vet has not heard of that - sorry.

Anyway we now appear to have a bit of infection adn thickening below this area so vet coming out tomorrow for a peak, question is he mentioned 3 treatments.
one is to use like frontline but cant diagnose how much is needed and a bit hit or miss then and costly.
the other two are injections one into the muscle- doramectin which he favours the other into the vein which he is less inclined to do.
both are not licensed for horses although he has used them successfully with better results from doramectin!

Any one had this done ??

not sure - Ill make my mind up tomorrow.... any info would really help

Hi - have had the injection done - it seemed to work and no side effects (sounds like it was doramectin) - I did not have any luck with frontline - the hair was so thick that apparently whatever we did, enough wasn't getting through (this was after clipping feathers off). Had it done a few times, and so have some friends at a nearby yard - also with no noticable side effects. Is that any help?

Cairo no matter what I used never 100% got rid of scabbing behind the knee all the time, I could keep it to a tiny pink spot and not scabbing up and occasionally completely gone with P&S.

Frontline is very effective and then using pig oil and sulphur - if you want the very long PM I do on keeping hairy horses with good feather and mite free, PM me and I will send it to you.

I have not used the injection, but my two youngsters have been P&S treated since I got them and no sign of anything nasty. The two older ones were cleared up with frontline and then P&S stopped it return.

Cairo's problem may also have been due to his compromised immune system from chemo.

Unfortunately I have found a lot of vets (particularly younger ones) don't know about the complaints of hairy heavy types - mallanders is a very common term.

What you do need to do is get the infection cleared up asap before you end up with thickened skin - my PM contains a link to a very good article on this.

Doramectin is drug in dectomax injection -goes under skin, needs re injection 3 weeks later, very effective - never had one not get better.(not licensed but extensively used)
The other injection is probably ivermectin and isn't very effective even injected weekly for 3 weeks.(again not licensed and less used to treat mites)

You sometimes get a bit of swelling around the injection site and you can see the lump where the injection goes under the skin but it doesn't seem to bother the horse and it goes fairly quickly.

Hi All,

Went with dectomax after long discussion with vet on friday - very mild case he said but 99.99% its chorioptic mange, will wait till 2nd application in 10 days and hope to then see an improvement....

so far so good - no swelling and we went for gentle hacks all weekend and he appears fine

thansk for all info

hi scottish miss get yourself a bottle of colloidal silver 10ppm
and spray the area well and you'll see the difference in no time.
hope this helps.
regards.
will.

www.equinescienceupdate.co.uk. Doramectin is used against internal and external parasites in cattle and sheep. It is stored in body fat and released slowly to give prolonged activity. A recent study considered the use of these two drugs for treating chorioptic mange in horses.

Mr David Rendle and colleagues at the Glasgow vet school assessed the response to treatment of seventeen cases of chorioptic mange in horses. They treated eight cases with doramectin (0.3 mg/kg, two doses by subcutaneous injection 14 days apart) and nine others with fipronil (0.25%, sprayed onto the lower legs.)

After two weeks, four of the doramectin-treated horses and eight of those treated with fipronil had improved. By four weeks none of the horses showed any behavioural signs of skin irritation. "I am unconvinced that one treatment is better than the other" Mr Rendle adds. "I find both equally effective."

No adverse reactions were noted in any animals. Some of the horses with heavily feathered legs were treated without being clipped. Despite that the treatments appeared to be effective. However, because of the small number if horses involved, that does not prove that clipping is unnecessary.
